In the drawings B indicates the slotted secondarymetal eye m together with the slotted, secondary porcelain .threadguidefixed therein, and B indicates the assembled initial metal eye m havingthe longitudinally slotted wall and being provided with the slottedinitial porcelain threadguide. See also Fig. 6.

seen that the protected first or initial nonmetallic slottedthread-guide member is mounted in and registers with the slot formed inthe shuttle body and is adapted to receive into and guide the strand orthread of yarn as it is drawn direct from the cop or supply; the threadbeing bent or deflected at an angle from the projecting outlet end 0 ofthe guide, without coming in contact with the metal eye, the threadpasses from the guide into the slitted and protected secondarynonmetallic guide positioned in the slitted secondary eye member 'mwithin the shuttle-body. The outer end of the last-named-guide extendsthrough the eye m and through the adjacent outer side of the shuttle;the reciprocatory movements of the shuttle, as in weaving, causing thethread to render freely through and from 40 side to side across themouth of the guide without wear and without engaging the metal eye,thereby increasing the efliciency of the shuttle and subjecting thethread to a more uniformdegree of tension or drag,

which acts to increase the quality of the woven fabric.

I claim,:- '1. The combination in a doom-shuttle, a

shuttle-body, means connected with the body By means of my improvementit will be located transversely for holding a limited amount of yarn, anopening cut in the shuttle-body for the passage of a strand of the yarn,initial and secondary tubular eyemembersfixed in the shuttle body, thesaid eye members being disposed at substantiall right angles to eachother,'the walls of the eye members being longitudinally slotted andcommunicating with said yarn passage, a pair of non-metallic yarn-guidemembers having longitudinally slotted walls, the said non-metallicguides being secured in and projecting from the yarn delivery ends ofthe respective said eye members, the slots formed in the guide membersbeing in open communication with the slots of the respective eyemembers, substantially as described, and for the purpose set forth.

2. In a loom-shuttle, a shuttle body provided with means adapted -forholding a supply of yarn, and a passage formed in the shuttle bodyadapted to receive the strand of yarn, the combination of an initialmetal tube or'eye positioned to receive the. am direct from said supply,a non-metallic guide member secured within said initial eye andprojecting from the terminal or outlet end of the eye, the walls of saidinitial eye and guide members being longitudinally'slitted and in opencommunication with each other and with said yarn-passage in the.shuttle:

body, a secondary metal eye member seated transversely in the shuttlebody, a nonmetallic yarn-guide member secured within the secondary eyeand extending from the outer end of the latter, and havingthe walls ofsaid secondary eye and its guide member longitudinally slitted and inopen communication with each other and with the said yarn passage formedin the shuttle body, substantiallyas described and for the purpose setforth.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
